Note 3: The output leakage is measured under the following conditions:
a) The Driver tristated
b) Power supply OFF, and the power pins shorted to Ground
c) Power supply OFF. Impedances between power pins open and power pins shorted to Ground.
Note 4: The output waveform should not show any signs of oscillations under any load variation between o.1VVss and 0.9Vss. The oscillation
allowed when VSS < 0.1VSS and Vss >0.9Vss shall be 10% of Vss.
Note 5: tfc1 thru trc4 shall be within ±20% of trc1 thru trc4 respectively.
Note 6: All pins are required to withstand parameter.
Note 7: Output pins are required to withstand fig.5 without any degradation to the circuit.
